Question

Azimuthal quantum number defines

• A. e/m ratio of electron
• B. angular momentum of electron
• C. spin of electron
• D. magnetic momentum of electron

Answer 1

Answer: (B)

Azimuthal quantum number defines the spatial distribution of electron cloud and angular mementum.

e.g. $l=0,\,\,\,\, s -$ sub sehll

$\,\,\,l =1, \,\,\,\,\,\,\,\,p -$ sub shell

$\,\,\,l =2, \,\,\,\,\,\,\,d -$ sub shell

Orbital angular momentum of an electron is calculated using the expression. $=\sqrt{l(l+1)} \frac{h}{2 \pi}$
